Abstract

PURPOSE:To omit both the position registration processing and the charge processing at the exchange side by adopting the constitution to detect the outgoing communication for a prescribed significant information part is made, and to stop the transmission function. CONSTITUTION:A call unit control section 28 to control a call unit being significant information stores an initial call unit in advance and call units stored in a call unit information storage means 29 are decremented by '1' when a charge signal is received through the connection to a line of an opposite party. When the remaining call unit reaches '0' during talking, and a charging signal is further inputted, power supply to a radio transmission reception section 20 and a dial signal generator 26 is interrupted with an end detection signal from a call unit discrimination means 32 to make the talking disable. Thus, it is not required for registration of position information or charge processing by an ID code for an exchange station side and the similar processing for a line of a public telephone set is enough.

Description

[Detailed description of the invention] Industrial application field of the present invention> The present invention relates to a wireless mobile phone.

<Prior Art and Issues to be Solved> Conventional mobile phones used in car phones, etc., use a mobile JR identification number (ID code) unique to the mobile phone to indicate which area they are in. The information is sent to the base station and used as location registration information in preparation for incoming calls.

However, current mobile phone systems require a relatively large amount of transmission power (several watts) because each area is quite large, and they also have a large built-in battery that allows them to be used even when removed from the car. Large and heavy;
It was not easy to carry and use.

In addition, the exchange must constantly monitor the area in which the mobile phone is located, register the location, and perform charge registration processing for the pre-registered mobile phone identification number (ID code). First, the exchange process has become extremely complex and the system has become enormous.

In order to alleviate these problems, a new mobile phone that can make calls with a small output by making the mobile phone only for making calls, omitting the location registration process on the exchange side, and increasing the number of base stations to reduce the area area. systems have been proposed in recent years.

However, even with this new system, the complexity of charge registration processing corresponding to the mobile device identification number (ID code) on the exchange side has not been resolved. Realizing this has become an important issue.

An object of the present invention is to provide a mobile phone that solves this problem.

Means for Solving the Problems> In order to solve the above problems, the mobile phone of the present invention includes: a valuable information storage means in which predetermined valuable information is stored in advance; Completion detection means for detecting that a predetermined amount of valuable information has been made for outgoing calls by the mobile phone based on the billing signal; and upon receiving the detection signal from the completion detection means, stopping at least the outgoing call function of the mobile phone. and a stopping means.

<Effect> Therefore, when an outgoing call is made for a predetermined amount of valuable information,
The stopping means stops at least the calling function.

Therefore, the user can make outgoing calls for a predetermined amount of valuable information.

Embodiments of the present invention> (Figures 1 and 2) An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram showing a mobile phone for making calls according to an embodiment, and FIG. 2 is a perspective view showing the appearance of the embodiment.

As shown in FIG. 2, this mobile phone 10 is formed thin and is composed of an upper housing 11 and a lower housing 12 that are foldably connected.

A display 13 and a protruding hook switch 14 are provided on the front part 11a of the upper housing 11, and the lower housing 1
A flat type dial switch 1 is installed on the front part 12a of 2.

When making a call, hold the phone close to your mouth.

Note that a telescopic antenna 16 is provided on the upper surface portion 11b of the upper housing 11.

Furthermore, when the mobile phone 10 is not in use, the upper housing 1 is
1 and the lower casing 12 at their respective front parts 11 a, 1
Fold it so that it becomes 2atfiffi and hook switch 1
4 is provided with a locking mechanism to maintain it in an on-hook state.

That is, as shown in FIG.
The locked state is maintained by the tip 17a of the locking piece 17 attached to slightly protrude toward the front from b locking into the locking groove 18 provided in the lower surface 12b of the lower housing 12. At the same time, the hook switch 14 is pushed by the front surface portion 12a of the lower housing 12 and enters the on-hook state.

The rear end 17b of the locking piece 17 is biased counterclockwise (in FIG. 3) by the spring 19 from the inside of the upper housing 11, so unless the rear end 17b is pushed from above, this The locked state is maintained.

FIG. 1 shows the circuit configuration of this mobile phone 10. As shown in FIG.

In FIG. 1, reference numeral 20 denotes a wireless transmitting/receiving unit that receives a signal from a base station through the antenna 16 and transmits a wireless signal to the base station.

22 is a duplexer for sharing the antenna 16 for transmission and reception; 23 is a transmission circuit that converts dial signals and call signals into radio signals and outputs them to the antenna 16; 24 is a transmitter that converts dial signals and call signals into radio signals and outputs them to the antenna 16; This is a receiving circuit that demodulates signals etc.

25 is a frequency control circuit that automatically controls the transmission and reception frequency of this mobile phone 10 based on the control signal received by the reception circuit 24.

26 is a dial switch 15.15,...1
A dial signal generator 27 outputs a dial signal corresponding to 5 to a transmitting circuit 23;
(consisting of a speaker and a microphone as described in ``ift'').

Reference numeral 28 is a frequency management unit for managing the frequency, which is valuable information, and the initial frequency (for example, 500 degrees) corresponding to the fee paid by the user when purchasing or renting this mobile phone is stored in advance. , is configured so that the stored frequency is decremented by "1" each time a billing signal is received from the base station side during a call.

Reference numeral 29 denotes a power information storage means in which an initial power is stored in advance.

Reference numeral 30 denotes a completion detecting means composed of a subtracting means 31 and a frequency determining means. This subtraction means 31 subtracts the frequency stored in the frequency information storage means 29 by "1" every time it receives the billing signal from the receiving circuit 24, and stores the subtraction result (remaining frequency) in the frequency information storage means 29. Let me remember it again. Further, the frequency determination means 32 sends an alarm signal to the handset 27 when the subtraction result of the subtraction means 31 becomes 110'' during a call.
When the charge signal is received continuously or when the hook switch 14 is switched from the OFF state to the ON state and the frequency is 0'', a completion detection signal is output.

33 is a display means for displaying the dial number of the other party and the power information stored in the power information storage means 29 on the display 13 as the remaining power.

34 is the power source for this mobile phone, which is powered by a rechargeable battery.

35 is a function stop switch that is connected in series with the hook switch 14 and cuts off the power supply to the dial signal generator 261t5 and the wireless transmitting/receiving section 20 in response to the completion detection signal from the frequency determining means 32.

Note that power is constantly supplied to the frequency management unit 28 regardless of the function stop switch 35.

Further, this power source 34 is charged enough to guarantee communication for the initial power stored in the power information storage means 29 in advance.

Next, the operation of this mobile phone will be explained.

When the folded mobile phone 10 is opened by pushing the rear end 17b of the locking piece 17, the hook switch 14 is turned on, power is supplied to the wireless transmitter/receiver 20 and the dial signal generator 26, and the call is made. Becomes ready.

User dial switch 15.15,...1
5 is operated in accordance with the dial number of the other party, this dial signal is converted into a radio signal by the transmitting circuit 23 and sent out from the antenna 16 (at this time, the telephone number of the other party is displayed on the display 13).

The base station in this area that receives this radio wave sends the received dial number information to the exchange and calls the other party.

When the other party answers, the line is connected, and a billing signal is sent from the base station to the mobile phone, just like a normal public telephone.

Note that the transmission and reception frequency of mobile phone 11110 is set in advance to a frequency corresponding to the line status in this area by a control signal from the base station side accompanying this transmission.

When the line with the other party is connected and the billing signal is received, the frequency stored in the frequency information storage means 29 is decreased by 1n.

At this time, if the remaining power is more than 1", it becomes possible to talk using the receiver 27.

During this call, billing signals are received by tying according to the line distance by region identification, and the frequency information stored in the frequency information storage means 29 decreases each time.

When the remaining power reaches “0” during a call, the power determination means 3
An alarm sound is generated by the alarm signal from 2, and the user is informed that there are no more degrees left (one degree worth of calls can be made).

When the remaining power reaches 0'' during a call and a billing signal is further input, a completion detection signal from the power determining means 32 cuts off the power supply to the wireless transmitter/receiver 20 and the dial signal generator 26, making it impossible to make a call. becomes.

Also, after finishing a call with the frequency being "0" and turning off the hook switch 14, the hook switch 14 can be turned off again.
Even if it is turned on, the transmission operation cannot be performed because the completion detection signal is being output.

Therefore, when this mobile phone 1110 is used, there is no need for the switching center to register location information or process charges based on ID codes, and only needs to perform the same processing as for public telephone lines.

Note that if a mobile phone is no longer usable, it can be used again by paying the fee again at a designated institution, re-memorizing the power information, and recharging the power.

Furthermore, if this mobile phone is constructed at a low cost, it is possible to discard the mobile phone and purchase a new one when it becomes unusable (the power runs out).

Other Embodiments of the Present Invention In the above embodiments, the present invention is applied to a mobile phone only for making calls, but it is also possible to apply the present invention to a conventional mobile phone for both making and receiving calls. In this case, the exchange i side may perform billing processing similar to that of a public telephone (location registration processing remains the same as before).

In addition, in the embodiment described above, the memorized frequency is subtracted by 1'' each time a billing signal is received, and it is detected whether a predetermined number of calls have been made by determining the result of the subtraction, but the frequency shown in FIG. Like the management section 28', the initial power storage means 40
The determining means 42 compares the initial frequency stored in the memory with the counted value from the counting means 41 that counts the number of times the billing signal has been received, and determines whether the counted value is 1 greater than the initial frequency (during a call) or The completion detection means 43 may be configured to output a completion detection signal when the count value and the initial frequency match when switching from on-hook to off-hook.

Further, in the above embodiment, the power supply to the wireless transmitter/receiver 20 and the dial signal generator @26 was cut off by the completion detection signal, but as shown in FIG. By switching ', the power supply 34 may be forcibly discharged by the resistor R at the same time as the power supply is cut off.

In addition, if a mobile phone is equipped with a charging rate table and a clock based on area identification, and the mobile phone performs the same charge registration process as when receiving a charging signal, a system that does not send charging signals from the switching center can be created. It can also correspond to

<Effects of the Present Invention> As described above, the mobile phone of the present invention is configured to detect that an outgoing call for a predetermined amount of valuable information has been made and to stop at least the outgoing call function. If the use of this mobile phone is permitted or sold in exchange for charges that include this valuable information, there will be no need for charge processing (billing registration) on the exchange side, and in particular, it will be possible to use the mobile phone only for making outgoing calls. If this system is used in a new mobile telephone system, it is possible to omit both the location registration process and charge processing on the exchange side, which were conventionally performed, and the burden on the exchange side can be significantly reduced.
